I've been playing around with two related vocabularies for describing
RSS-style syndication and weblogs (among other things), so the triples I
use to indicate the relationships between me, my website, and its feed
look something like this:

[1]  _:a foaf:name "David Menendez".
[2]  _:a foaf:weblog <http://www.eyrie.org/~zednenem/>.
[3]  _:a foaf:homepage <http://www.eyrie.org/~zednenem/>.
[4]  <http://www.eyrie.org/~zednenem/> rdf:type tdl:Weblog.
[5]  <http://www.eyrie.org/~zednenem/> foaf:maker _:a.
[6]  <http://www.eyrie.org/~zednenem/recent.rdf> rdf:type
[7]  <http://www.eyrie.org/~zednenem/recent.rdf> rdfchannel:syndicates 

Where 'tdl' is the Thread Description Language (cf.
<http://www.eyrie.org/~zednenem/2002/web-threads/>) and 'rdfchannel' is
RDF Channel (cf. <http://www.eyrie.org/~zednenem/2002/rdfchannel/>).

There is some redundancy, naturally, but that's a byproduct of using
three+ namespaces. (Note that triple 2 indicates that the page is my
weblog, whereas 3+4 state that my homepage *is* a weblog, and 4+5 state
that it is a weblog created by me; all potentially subtle distinctions
sure to drive developers crazy.)
